The machine is a Dell workstation with xeon processors. The OS is RHEL 4 AS x86_64 gcc version is 3.4.6 I checked out the llvm-gcc from svn, configured with ../llvm-gcc/configure --prefix=$HOME/llvm-gcc-install --enable-llvm=$HOME/llvmobj/ --enable-languages=c,c++ --enable-checking --disable-shared --disable-multilib and get the following error message: make

gcc 3.4.x builds LLVM incorrectly on x86_64. gcc 4.0 will get you much farther, but the llvm-test regression tests still have massive problems.

Alpine linux is a distribution that uses musl libc instead glibc. Here are my steps to reproduce: On Alpine linux, download LLVM, Clang, LLD 6.0.0 from releases.llvm.org, and build them from source. $ clang -c hello_world.c $ ld.lld --gc-sections -m elf_x86_64 -o hello_world /usr/lib/gcc/x86_64-alpine-linux-musl/6.4.0/../../../../lib/Scrt1.o

Hi, I am trying to cross compile release-10.x to AArch64 (target=aarch64-linux-gnu), and the directions listed at [1] are not completing the initial cmake step. I'm currently running Manjaro, with the aarch64-linux-gnu package (and associated binutils, headers, and glibc packages). My cmake command is cmake -DCMAKE_CROSSCOMPILING=True -DCMAKE_INSTALL_PREFIX=`realpath install`

Can you add `--reproduce=repro` to lld command line? That generates repro.tar in your current directory which contains all input files. And then please compress and upload it somewhere so that we can take a look.

I do all my LLVM stuff on x86_64 without trouble... I have a nightly tester up, and its only getting a few regressions currently, and I think some of those have to do with the radical changes going on in LLVM-land currently, and others with no one having done support for x86-64 in debugging output. (this is at least most of what I've seen, ymmv). Also, for the record, I have found both gcc

Hello, Thank you for your kind attention to my issue and your help. I changed the tool chain and tried again. And there is a little progress but still have some problem. Using --sysroot doesn't make clang use linker(ld) in the cross tool. Most important question is how I can make clang use cross tool linker. Let me show you my experiment and questions below. There are two questions. [Run]

Already have concerning gcc 3.4: http://llvm.org/bugs/show_bug.cgi?id=1056 As for llvm-test issues, quite frankly I don't know how well they're expected to work on x86_64. No one has jumped in and said they run fine on their x86_64 system. Maybe they're code generator bugs, or maybe they're portability issues for FreeBSD (though I never saw such massive problems with 32-bit

Hello Gergö, Joerg and people on our list With your kind answer, I tried to build a hello world program for ARM(arm-none-linux-gnueabi) on my x86-64 PC. Thank you we verified the generated bitcode. The only thing remained is linking. Let me brief what I did so far. 1. Built Clang/llvm in a way explained in http://clang.llvm.org/get_started.html on Ubuntu 11.10 x86-64 PC 2. Downloaded gcc-4.0

Hi, It looks like I have found a bug in LLD. Suppose DSO defines a global variable 'data' and initializes it by the address of function 'set_data' defined in the same DSO. If an executable file (linked by LLD) gets address of the '&set_data' function and compares it with a value stored in the 'data' variable it gets different result. If the executable is linked

Could you provide a list of all tests failing for you? You can just grep the output from make for 'FAILED!'. I've fixed 5 of them so far... 275 to go...

Hi all, I'd like to use LLVM 2.8 on a openSUSE 10.3 box and when I try to compile anything I get an error: martin at vm:~/project/backend> clang tutorial001.m -v -emit-llvm -o tutorial001 clang version 2.9 (trunk 122601) Target: x86_64-unknown-linux-gnu Thread model: posix "/usr/local/llvm/Debug+Asserts/bin/clang" -cc1 -triple x86_64-unknown-linux-gnu -emit-llvm-bc -disable-free

Hi Warren, You have the -m32 flag set, but it's still giving you this: > Warning: Generation of 64-bit code for a 32-bit processor requested. > Warning: 64-bit processors all have at least SSE2. But are you sure you want to compile the LLVM-GCC source? You should use the binaries unless absolutely necessary. -bw On May 24, 2007, at 10:34 PM, Warren Armstrong wrote: > Hi all,
